NTSB Safety Recommendation — Aviation
Recommendation text
TO THE NATIONAL WEATHER SERVICE: Work with the Federal Aviation Administration to (1) revise and harmonize the pilot weather report (PIREP) guidance in the Aeronautical Information Manual (AIM) and Advisory Circular (AC) 00-45H, including but not limited to the guidance and criteria for reporting low-level windshear (to specify airspeed gain or loss), turbulence (to specify in-cloud or out-of-cloud), and fair weather; and (2) revise the AIM to either include comprehensive PIREP-coding guidance or to clearly reference AC 00-45H as the source of this information.
In plain language (FlightFinder summary)
The National Weather Service is asked to collaborate with the Federal Aviation Administration to update and align pilot weather report (PIREP) guidance in the Aeronautical Information Manual (AIM) and Advisory Circular (AC) 00-45H, particularly for low-level windshear, turbulence, and fair weather reporting. Additionally, the AIM should be revised to either include comprehensive PIREP-coding instructions or to explicitly reference AC 00-45H as the source of that guidance.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
